2009-07-09UBIFS: small amendments in the LEB scanning codeArtem Bityutskiy
This patch fixes few minor things I've spotted while going through code: 1. Better document return codes 2. If 'ubifs_scan_a_node()' returns some thing we do not expect, treat this as an error. 3. Try to do recovery only when 'ubifs_scan()' returns %-EUCLEAN, not on any error. 4. If empty space starts at a non-aligned address, print a message.

2009-07-09UBIFS: dump a little more in case of corruptionsArtem Bityutskiy
In case of corruptions, dump 8192 bytes instead of 4096. The largest node is 4096+ bytes, so it is better to see a node boundary, which is not always possible when only 4096 bytes are printed.

2008-09-30UBIFS: add no_chk_data_crc mount optionAdrian Hunter
UBIFS read performance can be improved by skipping the CRC check when data nodes are read. This option can be used if the underlying media is considered to be highly reliable. Note that CRCs are always checked for metadata. Read speed on Arm platform with OneNAND goes from 19 MiB/s to 27 MiB/s with data CRC checking disabled.
